""When a clear reaction product` is obtainedthe heating is discontinued. The product is a stiff viscous resin.

Example 3 ne hundred parts of soy bean oil are heated :with one hundred parts of an epoxy resin havling van epoxy equivalent of 500 in the presence ,of one per cent lead naphthenate, while steam fis blown through the reaction mixture and the temperature maintained at 170 C. When a clear product is obtained thereaction is discontinued.

VThe. clear resin obtained may be reacted further with linseed oilvfatty acids. Example 4 One hundred parts of soy bean oil together 'With vtwenty-live parts of ethoxyline resin and Aone per cent sodium oleate are heated in the presence of direct' steam for a period of thirty minutes whereupon a clear oil product is obitain'ed. Although this reaction proceeds with 4great rapidity, the reaction product may gel on lcooling and the sodium catalyst remains in the oil product. This product accordingly is of limited value or rather limited in its eld of utility. The resinous oil products of the present invention are suitable for a number of purposes yin industry such as for the production of various 'esterication products in combination with carboxylic acids and for the production of etheri- "cation products with urea resins by which exceptionallystable coatings may be produced. The addition of conventional driers to the coating compositions may be desirable and the "hardening of the coatings may be effected by air drying or oven drying. Such products are `also suitable for the production of adhesives.

` It should be understood that the present invention isl not limited to the specific details herein given except where indicated and that the invention extends to all equivalent materials -and conditions which will occur to those skilled the art upon consideration of the terms and fbreadth of the claims appended hereto. I claim:

1. The process for producing resinous oil fproducts which comprises, reacting a fatty acid ester drying oil with an epoxy resin containing freeepoxy groups in the presence of steam at lresulting mass to a temperature of at least 150 IC.- .While introducing Steam ihrfughaie me 4 until reaction occurs and a clear reaction mass is obtained.

3. The process for producing resinous oil products which comprises, reacting a fatty acid ester drying oil with an epoxy resin containing free epoxy groups in the presence of steam and of an alcoholizing catalyst at a temperature of at least C.

4. The process for producing resinous oil products which comprises, mixing together a fatty acid ester drying oil, an epoxy resin containing free epoxy groups and an alcoholizing catalyst, and heating to a temperature of at least 150 C. while introducing steam, until reaction occurs and a clear reaction mass is obtained.

5. The Y process for producing resinous oil products which comprises, reacting a fatty acid ester drying oil with an epoxy resin containing free epoxy groups in the presence of steam and of a lead catalyst at a temperature of at least 150 C.

6. The process for producing resinous oil products which comprises, mixing a fatty acid ester drying oil with an epoxy resin containing free epoxy groups and a lead catalyst, and heating the resulting mass to a temperature of at least 150 C. while passing steam through said mass, until reaction occurs and a clear reaction mass is obtained.

7. The process for producing resinous oil products which comprises, reacting a fatty acid ester drying oil with an epoxy resin containing free epoxy groups in the presence of steam and a lead compound as a catalyst at a temperature of at least 150 C.

8. The process for producing resinous oil products which comprises, mixing together a fatty acid ester drying oil, an epoxy resin containing free epoxy groups and lead oxide as a catalyst, and heating the resulting mass to a temperature of at least 150 C. while introducing steam, until reactionyoccurs and a clear reaction mass is obtained.

9. The process for producing resinous oil products whichv comprises, reacting a fatty acid Aester drying oil with an epoxy resin of lower molecular weight containing free epoxy groups having an epoxide equivalent of 450 to 550`in the presence of steam and a lead catalyst at a temperature of atleast 150?` C.

10. The process for producing resinous oil productsA which comprises, mixing together a fatty acid ester drying oil, an epoxy resin` of lower molecular weight containing free epoxy groups having an epoxy equivalent of 450 to 550 and a lead compound catalyst, and heating the resulting mass to a temperature of at least 150 C. while introducing steam, until reaction occursA and a clear reaction mass is obtained.

11. The process for producing resinous oil products which comprises, mixing together linseed oi1an epoxy resin containingy free epoxy groups and a lead catalyst, heating the resulting mass to a temperature of from to 250 C. `While introducing steam into the reaction mixture, until reaction occurs and a clear reaction mass is obtained.
